Cloud options:

• Microsoft Azure offers credits for edu emails I think, and I think you can renew it annually. Also check their B1 servers. https://azure.microsoft.com/en-us/free/students
• Google free tiers: https://docs.cloud.google.com/free/docs/free-cloud-features#free-tier
• AWS | Not sure on this one, their website is confusing, but look into it: https://aws.amazon.com/education/awseducate/
• GitHub “student developer pack” https://education.github.com/pack
• Oracle cloud “always free” options, bottom of this page: https://www.oracle.com/cloud/free/
• InterServer(never heard of them before) offers 1 year of web hosting: https://my.interserver.net/student_signup.php

Self-Host locally options:

Honestly you can probably find a N100 or N150 miniPC online for cheap, like $200 USD or less. Install Proxmox(or just install Ubuntu or whatever), install Docker+DockHand, and then install Tailscale and from your laptop/computer with Tailscale on it. You’ll be able to remotely access it, spin up whatever servers you want, and I doubt your campus IT will even see anything due to the tailnet mesh.

If you’re not living on campus, then even better, just self host your own stuff.
